How can I make a class that can be converted into an int?

What are the internal methods that I need to define on any class so that
this code can work?

c = C("three")

i = int(c) # i is 3

I can handle the part of mapping "three" to 3, but I don't know what
internal method is called when int(c) happens.

For string conversion, I just define the __str__ method.  What's the
equivalent for int?  For float, too, while I'm at it?



A better way of running series of SAS programs:
